Title: A Process for Isolating Defects between Dielectrically Spaced Metallic Layers
IPC: C23F1/02
Filed: 1968-05-07
Abstract: 1,184,988. Thin-film capacitors. INTERNATIONAL BUSINESS MACHINES CORP. 7 May, 1968 [14 July, 1967], No. 21556/68. Heading H1M. In a thin film capacitor 1 comprising electrodes 3, 5 separated by dielectric 4, electrode 5 being separated from e.g. silicon dioxide substrate 6 by thin molybdenum layer 7, short circuit defects 10 indicated by deformations 2 in layer 3 are removed by etching away portions of electrode layer 3 in the region of the deformation only. As shown, a layer 8 of photo-resist material is spread over electrode layer 3 and preferably has a thickness less than the height of deformations 2. An etchant appropriate for the metal of layer 3 removes metal from around the defect, as shown in Fig. 2, due, it is believed, to the weakening of the etch resistance of layer 8 at the deformations.

Filed: 1929-07-22
Abstract: 328,510. Forgrove Machinery Co., Ltd., and Grover, F. July 22, 1929. Sheet-separators. - Labels or other sheets are fed from a pile O placed on a support E in a container C by means of a reciprocating suction member formed of two branches J, J<1> connected continuously by a tube M to a vacuum chamber. The members J, J<1> slide in cavities F, F<1> formed beneath the pile and a base B, and pass through shaped apertures in the sides A<1>, A<2> of the box. The upper surfaces N, N<4> of the branches J, J<1> are inclined so as to form spaces O, O<1> above them, and the reduction of air pressure in these spaces due to the withdrawal of air through passages K, K<1> and tube M causes the side edges of the bottom sheet to be drawn down on to the surfaces N, N<1>. This action is completed when the branches J, J<1> reach the position shown in Fig. 2 and an aperture H in the side A<1> of the container C is closed by a cover L. The suction action is set to bend down the edges of the bottom sheet only, and by moving the suction member to the left the sheet attached to the branches J, J' can move through the aperture H which is shaped to correspond to the form of a sheet with bent edges. Other sheets can not pass through this aperture, so that a final separation of the bottom sheet is effected by the movement of the members J, J<1> to the left. The separated sheet is detached from the members J, J<1> by means of plungers.

Abstract: 971,518. Pistons. FORD MOTOR CO. Ltd. May 31, 1963 [June 12, 1962], No. 22488/62. Heading F2T. The crown of an internal combustion engine piston 10 is so dimensioned that, in operation, the heat transfer through the two upper rings 17 and 18 is such that the temperatures of the rings are within 5‹ F. of each other. The piston has a combustion chamber cavity 20 in its crown and the underside surface 24 of the crown is concave. The dimensions of the sides 25 and the base of the cavity 20 are determined by a method shown diagrammatically in Fig. 2 and comprising a network of identical resistors 26 representing the thermal resistance of the piston material and uniformly arranged in a shape corresponding to a half-section of the piston. One side 27 of a voltage supply 28 is connected through identical resistors 29 to points 30 at the junctions of resistors 26 with the upper surface of the piston crown and the other side 31 is connected through two variable identical resistances 32 to resistors located in the positions of the piston ring grooves 39 and 40. The estimated temperature at a point 38 in the piston is represented by a voltage obtained by adjusting resistance 37 and resistances 32 are adjusted to provide a voltage at 39 corresponding to a reasonable first ring temperature. Resistors 26 are then added to or removed from the network, or the position of the ring grooves adjusted, until the voltages at 39 and 40 are the same, the shape then being the required piston shape. The resistance 36 represents the heat flow from the underside of the piston during operation. Specification 971,519 is referred to.
